what is your problem ??? post the code that works... i think that it dont work because you have to replase the if condition (if(mysql_num_rows($wynik) > 0) for a while condition (while($r = mysql_fetch_assoc($wynik)){) but before do the if result is > 0...

Try this:

$a = trim($_REQUEST['a']);  
$student = trim($_GET['student']);
if($a == 'edit' and !empty($id))
{  
    /* zapytanie do tabeli */  
    $wynik = mysql_query("SELECT * FROM table_name WHERE student='$student'")  
    or die('Błąd zapytania');  
    while($r = mysql_fetch_assoc($wynik))
	{
	   echo '<form action="edycja.php" method="post">
	   <input type="hidden" name="a" value="save" />
	   <input type="hidden" name="student" value="'.$student.'"/>
	   test1:<br />
	   <input type="text" name="test1" value="'.$r['test1'].'"/><br />
	   test2:<br />
	   <input type="text" name="test2" value="'.$r['test2'].'" /><br /> 
	   <input type="text" name="test3" value="'.$r['test3'].'" /><br />
	   <input type="submit" value="popraw" />
	   </form>';  
    }  
} 

elseif($a == 'save')
{  
    /* odbieramy zmienne z formularza */  
    $student = $_POST['student'];  
    $test1 = trim($_POST['test1']);  
    $test2 = trim($_POST['test2']);  
    $test3 = trim($_POST['test3']); 
    /* uaktualniamy tabelę test */  
    mysql_query("UPDATE test SET test1='$test1',  
    test2='$test2, test3='$test3' WHERE student='$student'")
